BACKGROUND: The CBCT imaging technique exhibits proper accuracy to determine the internal anatomy of teeth. Therefore, this technique can use to estimate age by measuring the amount of decrease in the volume of the pulpal cavity of teeth. The aim of the present study was to evaluate the correlation between chronological age and pulp-to-tooth volume ratios in anterior teeth with the use of the CBCT technique and to determine a regression model to estimate human age. MATERIAL AND METHODS: In this present descriptive-analytical study, 122 subjects (46 males and 76 females), with an age range of 13-70 years, were evaluated...

REVIEW
Tahmineh Farajkhoda
Conducting research on the stem cell lines might bring some worthy good to public. Human Stem Cells (hSCs) research has provided opportunities for scientific progresses and new therapies, but some complex ethical matters should be noticed to ensure that stem cell research is carried out in an ethically appropriate manner. The aim of this review article is to discuss the importance of stem cell research, code of ethics for stem cell research in Iran and ethical recommendation. Generation of stem cells for research from human embryo or adult stem cells, saving, maintenance and using of them are the main ethical, legal and jurisprudence concerns in Iran...

Obesity is a major risk factor for colorectal cancer and can accelerate Lgr5+ intestinal stem cell (ISC)-derived tumorigenesis after the inactivation of Apc However, whether non-canonical pathways involving PI3K-Akt signaling in ISCs can lead to tumor formation, and if this can be further exacerbated by obesity is unknown. Despite the synergy between Pten and Apc inactivation in epithelial cells on intestinal tumor formation, their combined role in Lgr5+-ISCs, which are the most rapidly dividing ISC population in the intestine, is unknown...

PURPOSE: To investigate the effect of buserelin on gonadal structure and function in adult male rats. METHODS: Twenty-four adult Wistar male rats were divided into three groups: two treated groups and controls. The first and second treated groups received 300 (low dose) and 500 (high dose) µg/kg buserelin, respectively, and the control group received normal saline. All groups were treated subcutaneously for five days. RESULTS: The seminiferous tubular epithelial thickness was significant decreased in the treated groups compared with those in the control...

BACKGROUND: It is necessary apical plug material to exhibit proper adaptation with the root canal walls. Presence of voids at the interface between the root canal wall and this material result in micro leakage, which might have a relationship with post treatment disease. The aim of the present study was to evaluate the effect of different mixing (manual and ultrasonic) and placement (manual and manual in association with indirect ultrasonic) method of Mineral Trioxide Aggregate (MTA) on the void count and dimension in the apical plug in natural teeth with simulated open apices...

BACKGROUND: The appropriate choice of a contraceptive method has been a major issue in reproductive health research. Cu T intrauterine device (Cu T IUD) has been introduced as one of the most effective contraceptive methods in the world, however, the relationship between prior use of Cu T IUD and secondary infertility has not been evaluated in Iran. To examine the association of Cu T-380A IUD and secondary infertility in Iran. MATERIALS AND METHODS: A retrospective cohort study was conducted from December 2010 to September 2011 in the Research and Clinical Center for Infertility, Shahid Sadoughi University of Medical Sciences, Yazd, Iran...

BACKGROUND: Prolylcarboxypeptidase (PRCP, EC:3.4.16.2) is a cardioprotective protease. Plasma PRCP levels are elevated in type 2 diabetes (T2D) mellitus and cardiovascular diseases. OBJECTIVE: Since diabetic cardiomyopathy is a late complication of uncontrolled diabetes, we tested the hypothesis that glucose and free fatty acid related risk factors for T2D mellitus and cardiovascular disease may reduce the cardioprotective property of PRCP. METHOD: 0 We examined the effects of glucose, saturated fatty acids, and unsaturated fatty acids on PRCP expression in cultured H9c2 cells as an in-vitro model for pharmacological studies...

In this work, novel chromenones linked to 1,2,3-triazole ring system were synthesized and evaluated for their anti-ChE activity. Among them, N-((1-(2-chlorobenzyl)-1H-1,2,3-triazol-5-yl)methyl)-8-methoxy-2-oxo-2H-chromene-3-carboxamide (6m) showed good anti-acetylcholinesterase activity (IC50=15.42μM). Also, compound 6m demonstrated neuroprotective effect against H2O2-induced cell death in PC12 neurons, however, it showed no beta-secretase (BACE1) inhibitory activity. Docking and kinetic studies separately confirmed dual binding activity of compound 6m since it targeted both the catalytic active site (CAS) and the peripheral anionic site (PAS) of AChE...

In order to develop effective anti-cholinesterase compounds, a novel series of pyrano[3',4':5,6]pyrano[2,3-b]quinolinones were designed, synthesized, and evaluated in vitro against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). All derivatives showed very good AChE inhibitory (AChEI) activity (IC50  = 0.37-5.62 μM) compared with rivastigmine (IC50  = 11.07 μM). Among them, 11-amino-12-(2,3-dichlorophenyl)-3-methyl-7,8,9,10-tetrahydropyrano[3',4':5,6]pyrano[2,3-b]quinolin-1(12H)-one (6f) displayed the best inhibitory activity...

Crimean-Congo hemorrhagic fever (CCHF) is a viral zoonotic disease which is endemic in Iran. The etiological agent of CCHF is an RNA virus belonging to the genus Nairovirus of the family Bunyaviridae. CCHF virus (CCHFV) can be transmitted to humans through bites from infected ticks and direct contact with infected blood or tissues. Although the disease has been observed in different age groups, the rate of disease is lower in children and elderly. This study was designed to characterize CCHFV-infected children in Iran...

A new series of tacrine-1,2,3-triazole hybrids were designed, synthesized, and evaluated as potent dual cholinesterase inhibitors. Most of synthesized compounds showed good in vitro inhibitory activities toward both acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Among them, 7-chloro-N-((1-(4-methoxybenzyl)-1H-1,2,3-triazol-4-yl)methyl)-1,2,3,4-tetrahydroacridin-9-amine (5l) was found to be the most potent anti-AChE derivative (IC50 = 0.521 μM) and N-((1-(4-methoxybenzyl)-1H-1,2,3-triazol-4-yl)methyl)-1,2,3,4-tetrahydroacridin-9-amine (5j) demonstrated the best anti-BChE activity (IC50 = 0...

Groebke-Blackburn-Bienayme reaction has been utilized for the synthesis of new imidazo[1,2-a]pyrimidine derivatives as novel anticancer agents. The cytotoxic activities of compounds were evaluated against human cancer cell lines including MCF-7, T-47D, and MDA-MB-231, compared with etoposide as the standard drug. Among the tested compounds, hydroxy- and/or methoxy-phenyl derivatives (6a-c and 6k) with IC50 values of 6.72-14.36 μm were more potent than etoposide against all cell lines. The acridine orange/ethidium bromide double staining and DNA fragmentation studies demonstrated that the cytotoxic effect of 3-hydroxy-4-methoxyphenyl derivative 6c is associated with apoptosis in cancer cells...
